Hair Follicle Drug Testing - Wright, IA

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug use by capturing biomarkers within its growing strands. When sourced near the scalp, a hair sample can show a history of usage spanning up to three months for both alcohol and drugs. The collection process is straightforward, with minimal risk of tampering, and samples are easy to ship.

A 1.5-inch segment comprising roughly 200 hair strands (comparable in thickness to a #2 pencil) nearest the scalp can yield 100mg of hair, which is the optimal quantity for both screening and confirming results. For EtG, additional testing, or examinations beyond 10 panels, a sample weighing 150mg is advised. It's recommended to measure the sample with a jeweler’s scale. In the absence of scalp hair, equivalent body hair can be gathered. References to head hair specifically mean scalp hair. Body hair includes all other types (such as facial and axillary hair).

Process Overview

There are four fundamental steps in the lab processing of drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab's infrastructure. This step ensures the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary data input not covered by an electronic chain of custody system.

Screening offers an initial rapid assessment for substance abuse. Although Screening is a cost-efficient approach to eliminate drug usage in most samples, any positive screen must be verified to be court-admissible. Samples that test presumptively positive in Screening require a follow-up confirmation.

Should a sample yield a presumptive positive result during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are removed from hair, albeit at lower concentrations than other methods such as urine or oral fluid, which makes hair drug tests the most challenging to execute.

Any positive findings from Screening are validated through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing prior to confirmation as necessary. Each step of the laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair guidelines, and in accordance with the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug consumption for up to 90 days, in contrast to urine tests that have shorter detection periods.
• Resistance to tampering: Hair drug tests are challenging to manipulate, resulting in more reliable outcomes.
• Chronological data: It can chronicle drug use patterns over time, beyond recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs tend to become detectable in hair only after 5-7 days.
• Cost: Hair drug tests are typically pricier than other drug testing techniques.
• Result variability: Elements like hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests," these tests analyze the actual hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Advantages Over Urine Tests: In Wright, IA, hair follicle tests offer superior detection compared to traditional urine testing. They provide more accurate results, ensuring a greater level of reliability in identifying drug use over extended periods.
